THE EASIEST CARSEAT TO INSTALL (Grandma-proof): Britax Poplar S Convertible Car Seat

As a solo parent with no co-parent, I knew nothing when it came to carseats except that you have to get one. Even though this one requires watching a video to remove and reinstall the carseat cover every time I want to deep-deep-clean it, my toddler recently projectile vomited in the car en route to school and put it to the test. You can easily get rid of the accumulated snack crumbs by hosing the carseat frame down.
